Introduction:

There are a lot of mobile display technologies, and some of them are CSTN, TFT, TFD, OLED, AMOLED Display, capacitive touch screen and Resistive touch screen. Among them, the most preferred ones are LCD, AMOLED display, and IPS display technologies. Here we are trying to draw a comparison between the three and also explain where and how they differ.

LCD:

LCD

  • The term LCD stands for Liquid Crystal Display. It is the most commonly used display type among mobile phones. This is because it consumes low power and but has good image quality. It also enables the user to read under direct sunlight.
  • Pixel is the smallest element of an image. Some of the display types under LCD are STN (Super Twisted Nematic), TFT (Thin Film Transistor) and TFD (Thin Film Diode). These displays differ based on cost, power consumption, and image quality.
  • The disadvantages of LCD screen are the slow response time and poor screen uniformity. It also has only limited viewing angle and the contrast, brightness and color keep varying. The screen has to be either at 90 degrees or 120 degrees and not more than that.

AMOLED display:

AMOLED display

  • The term AMOLED is an acronym for the phrase Active-Matrix Organic Light-Emitting Diode. This technology is used on the display screen of smart devices like the watch, mobiles, television, and laptops.
  • The OLED is a type of thin film display technology. The organic particles form an electroluminescent material. So the Active Matrix is a technology that adds a thin film behind which supports quick activation of pixels. The motive of AMOLED display is to walk devices through the low-power, low-cost yet large size applications.
  • Though AMOLED display had a warm welcome, it has its own disadvantages. The red and green OLED films last longer than the blue ones, so a specific pixel fades faster than others. The AMOLED display is prone to screen burn-in which leaves an indelible imprint of the over used colors.

IPS:

IPS

  • IPS stands for In-Plane Switching. It is again a screen technology that is used for LCD screen. When the Nematics display type of LCD screens came in it had a lot of complaints. So IPS was designed to solve the problems of twisted nematics field effect.
  • After the IPS technology was installed, the display was consistent and accurate from all angles. They didn’t show up tailing when touched.
  • However, they require 15% more power than the twisted Nematics panels and were quite expensive. Though it was a revised version, the IPS screen took a long time to respond.
